Website Caching: A Way to Faster Access

Web cache

Website caching is one of the most important technologies used by every web development company to make your website fast and reduce the bandwidth. It makes websites extremely fast which leads to better SEO scores and better user experience. Web caching means keeping data in storage to allow retrieval of data without requesting it from the original resources if the data will not be changing frequently.

In computer science, it reduces the delay of data traveling from the data storage system to the user. Websites are generally viewed hundreds, thousands and millions of time in every month. Each time, when a browser requests a web page then the server has to retrieve the data from the website. During that period, the server has to perform multiple complex calculations. The relative site retrieves the latest posts, images, find the sidebar widgets, generates header and footer etc. It stores the copies of the documents passing through it. Web caches hold the place between the web server and web browser where the resources have been copied in the form of HTML pages, images etc. when a client requests the resources, instead of forwarding requests to the web server the web cache will return it itself.
